The structures of the title compounds, [PtCl(2)(C(7)H(5)N(3)O(2)S)(2)].4C(3)H(7)NO, (I), and [Pt(C(3)H(5)N(3)S)(4)][PtCl(6)].2C(3)H(7)NO, (II), respectively, comprise square-planar Pt(II) centres. In the cation and anion of (II), the Pt atoms lie on independent inversion centres. For (I), the metal atom is N-bonded to two trans organic ligands and also bonded to two Cl atoms, whereas in (II), the Pt atom is N-bonded to four organic ligands, the charge being balanced by the presence of an additional PtCl(6) species (from the starting material). Both structures contain dimethylformamide solvate molecules, four in the asymmetric unit of (I) and one in (II), which are involved in the hydrogen-bonding network via N-H.X and C-H.X associations.
标题化合物[PtCl₂(C₇H₅N₃O₂S)₂]·4C₃H₇NO（I）和[Pt(C₃H₅N₃S)₄][PtCl₆]·2C₃H₇NO（II）的结构分别包含平面正方形的Pt(II)中心。在（II）的阳离子和阴离子中，Pt原子位于独立的反演中心上。对于（I），金属原子通过N键与两个反式有机配体相连，并且还与两个Cl原子键合，而在（II）中，Pt原子通过N键与四个有机配体相连，电荷由额外的[PtCl₆]²⁻物种（来自起始原料）平衡。两种结构均包含二甲基甲酰胺溶剂化物分子，（I）的不对称单元中有四个，（II）中有一个，它们通过N-H···X和C-H···X缔合参与氢键网络。
